COMBINATION MAGNET AND PRIMARY VALVE.

Application filed January 19, 1927. Serial No. 162,129.

This invention relates to improvements in pipe organs, especially in the valve mechanism for controlling the passage of air to the pipes, and it consists in the constructions, combinations and arrangements herein de scribed and claimed.

An object of the invention is to provide a unit in which the primary valve and the electro-magnet for actuating it are so combined that the installation'of the unit in the wind chest of an organ at once accomplishes the installation of the essential parts for con trolling the flow of air to an organ pipe.

A further object of the invention is to provide a unit of the character described, in which the structure is so simplified that the cost of manufacture has been reduced to a minimum, this, however, without the sacri fice of any essential elements.

Other objects and. advantages appear in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a cross section of an organ wind. chest illustrating the installation therein ot the improved unitary or combined valve and magnet, r

it possible to quickly and accurately install the essential'air control element of an organ pipe in the wind chest of an organ.

In carrying out the invention, provision is i made of a base generally indicated 1 which, being hollow, as shown in Figure 2, provides the receptacle or casing for the primary valve 2. The valve 2 is thus distinguished because its function precedes that of the secondary or organ pip valve 3. The latter controls the passage of air from the wind chest at to the orifice 5 of an organ pipe 6.

Attached to the base 1 by integral or other formation is an exhaust tube 7. This tube has a slight continuation at 8 on the interior of the base providing a seat upon which the 7 primary valve 2 is normally held by the pres sure of air within the wind chest and by spring pressure. The upper exposed end of the tube 7 has a flange 9 receiving suitable fastening means 10 by which the unit is attached in part to a center of the wind chest. A bracket 11 completes the mounting of the unit upon said member. The exhaust tube 7 communicates with an opening 12 through which air on the inside of the base or casing 1 may exhaust to atmosphere.

A short externally threaded tube 13 serves as the connector between the base 1 and the rigid half 14 of a pufl which includes the flexible diaphragm 15 by which the secondary Theedge of the diaphragm is clamped upon the rigid halt 14 of the puff by means of a. ring 16. The bracket 11 is held in position between the base 1 and the rigid half 14; of the puff, it

v beingevident that should the putt become loose upon the base 1 it is only necessary to turn the half 14 in the right direction thereby screwing down tight upon the bracket 11 and, upon the base 1. The tube 13 extends sufficiently high within the ri id half 14 to secured to the base by screws 19 or other wise, the screws passing through an outstandmg lug both upon the base and cover. An externally threaded tube 20 which is located on the same axis with the exhaust tube 7 provides a complementary valve seat to the seat 8. The valve tube may be screwed 1n and out upon the cover 18 to effect ad ustment in respect to the primary valve 2, the adjust- 7 known as a magnetbase, this base being interposed between the core of the magnet and cover 18 of the base. lhe magnet base has a bracket which has pendant ears 7) constituting part of a specialelectric circuit.

A combined armature 26 and valve lever 27 is pivoted at 28 between the ears 25, the lever 27 carryinga block 27 a (Fig. 7) fitting between the ears 25 and being provided with ears 25 for the purpose of receiving the pivot pin 28 as shown. The armature 26 is secured to the lever 27 and extends into proximity with the extremity of the pole of the electromagnetso that energization of the electromagnet will attract the armature and rock it upon its pivot. The lever 27 is apertured at its extremity as at 29 to receive the stem 30 of the primary valve, and at 29 to receive the fixed rod 29 carrying a spring 29 to hold the primary valve seated. The end of the valve stem'is threaded to receive a pair of Washers 31 between which the lever 27 is situated. Adjustment of the valve stem may be made in respect to the lever by turning the washers up or down. i i

Fig. 4 illustrates a modification which differs in construction from the form in Figs.

1 and 2 only in that the secondary valve 3 is operated by a pneumatic rather than the diaphragm of a so-called putt, and that the electromagnet 22 is mounted directly upon the cover 18 of the base 1. All parts of a construction similar to that inFigs. 1 and 2 are designated by corresponding reference nu- Inerals. The spring 17 which may be regarded as the equivalent of the spring 17 in Fig. 2 is mounted on the outside of the pneumat-ic' where it is readily accessible of being carried by a stem 17 which in turn has appropriate swivel supports 17 upon arms 17 extending from the upper and lower portions 7 enter the organ pipe 6 from the wind chest 4.

'An extension 34 of the cover 18 provides a place at which the magnet 22 is mounted by means of the screw 23. It is noted that the magnet base 24 (Fig. 2) is now omitted and that the hinge bracket having the pendant ears 25 are attached directly to the base cover.

Electric current to be sent through the magnet 22 by any desired means, the means herein employed consisting or an organ key 35 (Figs. 1 to 5 inclusive) which has asso ciatedcontacts 36 and 37 connected with wires 38 and 39*leading to the terminals of the magnet. The wire 38 embraces a suitable source of current 40. Depression of the organ key will close an electrical circuit which can be readily traced over the foregoing elements causing energization of the electromagnet and attraction of the armature 26.

Figure 5 illustrates a modification in which suitably secured at 26 to one of the members of the wind chest serves as a mounting for an electromagnet 47, the electromagnet being secured by means of a screw 48. Ears 49, pendant from the base provide a mounting for the pivot of the combined armature 51 and valve arm 52. Thelatter carries the organ pipe valve 44 as shown. A stem 53 with an adjustable stop 54 limits the rocking movement of the valve arm. A second stem 55 has an adjustable abutment 56against which one end of a light spring 57 rests. The other end of the spring bears against the under side of the valve arm and holds the valve in a normally closed position against the orifice 42.

The operation is readily understood. In Figs. 1 and 4 the internal air pressure of the wind chest 4 pressure of the spring 29 holds the primary valve 2seated against the end of the exhaust tube 7, thus leaving the valve tube 20 uncovered and admitting compressed air from the wind chest to the interior of the base or casing 1 whence it enters the putt in Figs. 1 and 2 or the pneumatic in Fig. 4 and holds the secondary or organ pipe valve seated against the orifice 5 so that wind chest air can not reach theorgan pipe 6. A depression of the organ key 35 will close the electrical circuit illustrated causing energization of the electromagnet 22 and the attraction or" the armature 26. The rocking otthe combined armature and valve lever pulls the primary valve 2 down into seating position upon the valve tube 20 so that the interior of the base or casing 1 is placed in communication with the atmosphere through the exhaust tube 7 and reestablishment oi the original condition.

It is to be noted that the various adjustments which may be made are essential to the prompt and accurate operation of the device. These adjustments are effected at the washers 31 whereby the relationship of the stem 30 to the valve lever 27 may be altered to suit requirements, and also of the primary valve 2 upon the stem 30.

The foregoing action may be described .as being indirect in that it requires the un seating oi the primary valve 2 before the secondary valve 3 becomes unseated. But in Fig. 5 the action is direct. Energization of the electromagnet 47 causes an immediate un- 35 seating of the organ pipe valve a l so that air from the wind chest atl is at once admitted to the orifice 42 and thus to the organ pipe d3. In any case the construction is compact and simple, making iteasy to install the device 30 and as easy to take it out for the purpose of replacement or repair.

In order to avoid the entrance of foreign matter to the exhaust port or opening 7, provision is made or" a dust cap 58, this consisting merely of a cover slotted crosswise on the under side as at 59.

While the construction and arrangement of the improved combination magnet and valves is that of a generally preferred form, obvious- 1y modifications and changes may be made without departing from the spirit of the invention or the scope of the claims.
